.NET Core Linux cannot convert PDF to Tiff

Aspose.PDF Product Family
1

I’m unable to convert a PDF or page of a PDF to a bitonal tiff. It throws an error about the Gdip.CheckStatus not being implemented. I’m using Ubuntu 19.04 64-bit with a 30 day evaluation license. The code I used is the same one in the documentation.

Any ideas on if this will work or if its a limitation of TIFFs on Linux and the GDI+ in .NET Core?

//Snippet 1 - fails
var bytes = File.ReadAllBytes("/home/shawn/test.pdf");
using (var stream = new MemoryStream(bytes))
{

            PdfConverter pdfConverter = new PdfConverter();
            Resolution resolution = new Resolution(300);
            pdfConverter.Resolution = resolution;

            pdfConverter.BindPdf(stream);
            pdfConverter.DoConvert();

            try
            {
                TiffSettings tiffSettings = new TiffSettings();

                tiffSettings.Compression = CompressionType.CCITT4;
                pdfConverter.SaveAsTIFF("/home/shawn/output.tiff", tiffSettings);
            }

Thank you for elaborating further.

Would you please also share a ZIP containing sample application including the project file because project configurations are also required in order to reproduce this in our environment. We will then proceed further to assist you.

We are looking into this scenario. In the meanwhile, can you please follow below steps and then share you kind feedback with us.

  1. Try installing “System.Drawing.Common” from NuGet

  2. If it does not resolve the issue, try the following steps:

  • Install .NetCore SDK
  • Install libgdiplus

The installation command to install libgdiplus is as follows

sudo apt-get install libgdiplus
ln -s libgdiplus.so gdiplus.dll
  1. Try the following command as well:
  • apt-get install libc6-dev

Please share your findings after trying these suggestions.
